Hong Kong University of Science and Technology (Guangzhou)

I am currently a first-year MPhil in Data Science and Analysis (DSA) at the Hong Kong University of Science and Technology (Guangzhou), with Professor Yuyu Luo and Professor Nan Tang as my supervisors. Meanwhile, my second supervisor is Professor Tongyi Zhang, who is also an Academician of the Chinese Academy of Sciences. Previously, I obtained my bachelor’s degree from Nanjing University of Information Science and Technology in 2024. My research interests are Large Language Model(LLM) reasoning, post-training of LLMs, and how to use LLMs for more human-friendly visualization systems. Currently, my work is also devoted to exploring the application of post-training paradigms such as RL in the agent field.
